All of the files that I choose on my MacBook are synced to Box at work. I have many personal files in the Box cloud, and I would like to purchase a second cloud sync service to allow me to keep my personal files. Is there any problem running two sync services at the same time? I really like Box, but I want to use a different cloud service since I foresee problems running Box twice at the same time. That would be problematic. Can you recommend a great cloud service with sync ability like Box? Thanks!
